Mermaid node with links not clickable

[leonstafford]

As per the Interaction section in the Mermaid docs

The following markup will create linkable nodes:

click downloading "/en/troubleshooting/downloading/"

This does indeed create clickable nodes within the Learn theme, but without showing a cursor: pointer style.

I have confirmed that by:

• adding .node.clickable { cursor: pointer; } to custom CSS and adding the clickable class via FireFox's inspector, the node's will show the expected pointer cursor on hover.

Not sure if this is simply a library update or what is required, but will start taking a look, as I'm loving these Mermaid charts!
